Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable system is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Sep 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate this vulnerability, organizations and users should: 1) Monitor for updates from ZhenShi and apply patches promptly once available. 2) Restrict physical and logical access to devices running the Mibro Fit App to trusted users only. 3) Employ mobile device management (MDM) solutions to enforce app usage policies and restrict installation of untrusted apps that could exploit this vulnerability. 4) Use Android security features such as app permission controls and component export restrictions to limit exposure. 5) Conduct regular security audits of installed apps to identify and remediate improperly exported components. 6) Educate users about the risks of local device compromise and encourage strong device authentication mechanisms. 7) Consider isolating devices running the vulnerable app from sensitive networks or data where feasible. These steps go beyond generic advice by focusing on controlling local access, monitoring app behavior, and enforcing organizational policies to reduce exploitation risk in the absence of an official patch.

Description

A flaw has been found in ZhenShi Mibro Fit App 1.6.3.17499 on Android. This impacts an unknown function of the file AndroidManifest.xml of the component com.xiaoxun.xunoversea.mibrofit. This manipulation causes improper export of android application components. The attack requires local access. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, especially those involved in health, fitness, or IoT device management, this vulnerability poses a risk to the confidentiality and integrity of user data collected by the Mibro Fit App. If employees or customers use the vulnerable app on corporate or personal devices connected to organizational networks, attackers with local access could leverage this flaw to access or manipulate sensitive health data or gain a foothold for lateral movement. This could lead to privacy violations under GDPR, reputational damage, and potential regulatory penalties. The impact is heightened in sectors handling sensitive personal data such as healthcare providers, insurance companies, and wellness service providers. Additionally, organizations that distribute or support the Mibro Fit App as part of their service offerings may face increased liability and operational risks. However, the requirement for local access limits remote exploitation, somewhat reducing the overall threat level to organizations unless devices are physically compromised or infected with malware that can exploit this vulnerability locally.
